Abstract: A pump control system includes a pump operable via actuation of an actuator that moves an actuating element to cause the pump to generate an intake stroke and a discharge stroke to pump media along a pipe or conduit. A sensor is disposed at the actuator and is operable to sense the position of the actuating element during operation of the actuator and pump. A controller is operable to control the actuator. The controller, responsive to an output of the sensor, determines the current position of the actuating element and automatically controls the actuator to provide a selected performance of the pump.
